ALBANY, N.Y. (CBSNewYork/AP) — Standard & Poor’s Ratings Service has downgraded the credit rating for the New York State Thruway Authority, over concerns about toll increases after the new Tappan Zee Bridge is complete.

The rating service said Tuesday it has reduced the rating for bonds sold by the Thruway Authority from A+ to A. The agency said it acted because the authority has not detailed how much tolls will rise and traffic volume appears to be declining.

Thruway officials say the increase will be decided after the state learns if it will get a $1.5 billion federal loan.

Currently, the toll for the current Tappan Zee is $5. And the Thruway Authority estimated last year — under the previous hopes for federal funding — that when the new bridge is completed in 2018, the toll could nearly triple to about $14, which Cuomo said was too high.

Many commuters told WCBS 880’s Sean Adams they agree that much of an increase would hurt.
